Self-medication practices to prevent or manage COVID-19: A systematic review.

Abstract

BackgroundPrevious studies have assessed the prevalence and characteristics of self-medication in COVID-19. However, no systematic review has summarized their findings.ObjectiveWe conducted a systematic review to assess the prevalence of self-medication to prevent or manage COVID-19.MethodsWe used different keywords and searched studies published in PubMed, Scopus, Web of Science, Embase, two preprint repositories, Google, and Google Scholar. We included studies that reported original data and assessed self-medication to prevent or manage COVID-19. The risk of bias was assessed using the Newcastle-Ottawa Scale (NOS) modified for cross-sectional studies.ResultsWe identified eight studies, all studies were cross-sectional, and only one detailed the question used to assess self-medication. The recall period was heterogeneous across studies. Of the eight studies, seven assessed self-medication without focusing on a specific symptom: four performed in the general population (self-medication prevalence ranged between ConclusionsStudies that assessed self-medication for COVID-19 found heterogeneous results regarding self-medication prevalence and medications used. More well-designed and adequately reported studies are warranted to assess this topic.
